ULTRAX Aerospace Passive Electrical Troubleshooting (PET) Modules are powerful and easy-to-understand troubleshooting systems that help maintainers quickly diagnose, identify, and locate problems in complex electrical systems.

• Get insights into the interrelationship of connections in a system
• Develop an understanding of the properties of each wire
• Examine electrical characteristics of LRUs connected throughout the system

EIS™

ULTRAX’s EIS™ technology (Electrical Information System) leverages the same powerful analytical process used by DNA researchers to diagnose patients, but we use it to highlight abnormalities hidden in complex electrical systems.

PET Modules™

PET Modules use the extensive EIS database to highlight anomalies in interconnected electrical systems. This is done with failed systems in an unpowered state: hence the name “Passive Electrical Troubleshooting”. Each PET Module is tailored to interconnect directly into a specific system, i.e. T700 Turbine Engine system, H-60 AFCS system, CH-47 FADEC, etc. PET Modules turn the maintainers’ focus to areas of concern providing exact pins and physical locations of an anomaly, whether it be a defect within an LRU, interconnect wiring, installation of an MWO, etc. Rely on a PET Module to help find insights to a problem when BIT has not provided adequate fault location.

 PET Scanner™

PET Modules rely on a device called the PET Scanner to interrogate a defective system. Relying on EIS technology, the PET Scanner is able to discover insights within the complex nature of the interconnected wires in the electrical system. It uses measurement technology that is as safe as a multimeter to examine the entire distributed electrical system with all LRUs connected.

The PET Scanner makes more than 1.6 million measurements to clearly characterize the system and reports to the maintainer its findings using plain English, schematics and physical fault locations (in the form of images).
